Technical field
The invention belongs to optical engineering technical field is and in particular to a kind of large caliber reflecting mirror primary mirror mounting structure.
Background technology
Principal reflection mirror directly determines as the key element in the reflective primary optical system of heavy caliber camera, its surface figure accuracy
The image quality of telescope.With the increase of optical system bore, the diameter of reflecting mirror and weight can increase, in terrestrial gravitation
In the presence of, primary mirror can deform, thus causing the image quality of optical system to reduce.In order to reduce the deformation of primary mirror,
The position of primary mirror support structure stress point is determined so as to deformation is minimum by analysis, thus obtaining higher main mirror face precision.
For ensureing the surface figure accuracy of primary mirror so as to be reduced to acceptable limit from the impact conducted oneself with dignity or by impact, design a fit
The primary mirror support structure of reason is particularly important.
The central shaft positioning and mounting structure of the commonly used shaft hole matching of camera reflective optical system that ground uses at present
As Fig. 1, shown in 2, this supporting construction has the disadvantage that under current assembly technology：
1. shaft hole matching realizes the radially, axially connection support to primary mirror, in the case that range of temperature is larger, easily
Lead to seriously reduce the surface figure accuracy of reflecting mirror due to the central shaft additional stress causing of expanding with heat and contract with cold, cause system imaging matter
The decline of amount；
2. gluing area is big, and gum spot uniformity is uncontrollable, is easily caused primary mirror mating holes circumference annulus gluing segment stress not
All, affect main mirror face；
3. shaft hole matching finally adopts gluing fixation, is completed by disposable injecting glue, not readily removable glue after curable adhesive layer, increases
Tear glue difficulty open and debug risk.
Content of the invention
It is an object of the invention to overcoming the deficiencies in the prior art, a kind of rigidity height, good environmental adaptability being provided, easily assembles
Novel camera reflecting mirror support structure.
A kind of heavy caliber camera Reflecting mirror installation structure of the present invention, including reflecting mirror and central shaft, its special character exists
In：
Described central shaft has Auxiliary support section and main supporting section, between described Auxiliary support section and mirror center hole axle hole
Gap is joined merga pass injecting glue and is carried out auxiliary and is fastenedly connected；
Described main supporting section is located at back of reflecting mirror, and described main supporting section is main support face near the face of back of reflecting mirror,
Multiple mounting grooves are provided with described main support face；
Described Reflecting mirror installation structure also includes multiple viscose glue pressure heads, and the plurality of viscose glue pressure head correspondence is arranged on multiple peaces
In tankage；
It is fixedly connected by binding agent between described back of reflecting mirror and multiple viscose glue pressure heads.
It is the basic structure of the present invention above, based on this basic structure, the present invention also makes following optimization and limits：
The fit clearance in above-mentioned Auxiliary support section and mirror center hole controls between 0.1-0.2mm.
Above-mentioned Auxiliary support section is peripherally disposed the viscose glue boss parallel with axle body, along viscose glue boss centre normal
Direction is provided with hole for injecting glue, and viscose glue boss surface is along the circumferential direction provided with the guiding gutter of square crossing with axle body direction, intersects
Point passes through hole for injecting glue.
Above-mentioned viscose glue pressure head is multidiameter form, and the periphery at big end is provided with anti-rotational boss；Small end is viscose glue end, big end
Peripherally disposed with small end ladder have stress-removal groove.
Above-mentioned big end is inwardly provided with screwed hole along its axial end；
Described main supporting section along its axially arranged have and the end through hole that communicates of screwed hole greatly,
Described supporting section also includes and viscose glue boss quantity identical screw, and described screw is worn outside main supporting section successively
Cross through hole compression viscose glue boss of threadeding with screwed hole.
Compared with prior art, advantage is the present invention：
1st, the present invention passes through the main support in back, axis hole Auxiliary support, improves mirror support efficiency, increases reflecting mirror
Support safety coefficient.
2nd, back support is completed by the gluing pressure head being installed on reflecting mirror axle it is achieved that gum spot size is controlled, eliminates
Because gum spot differs in size the reflecting mirror surface shape error that the additional stress inequality that reflecting mirror is produced causes, pressure head viscose head
Setting stress-removal groove, ensure dynamic with static structure rigidity while, can effectively eliminate camera body stress and deform right
The impact of reflecting mirror, reduces the impacts to reflecting mirror surface shape for the factor such as temperature change, gravity.
3rd, reflecting mirror axle and gluing pressure head are bolted connection, and improve reflecting mirror easy in the case of gluing error
Tearing open property, thus reduce resetting difficulty and risk.
4th, the clearance control of axis hole Auxiliary support is between 0.1-0.2mm, it is to avoid lead because reflecting mirror axle expands with heat and contract with cold
The reflecting mirror surface shape trueness error causing, is provided with guiding gutter at splicing face simultaneously, is conducive to adhesive glue uniformly to spread, formed all
Cloth gum spot, improves surface figure accuracy.
